Not able to create user

while i was testing to create user using management API using access token, in postman i am getting the error like this:
{
“statusCode”: 400,
“error”: “Bad Request”,
“message”: “Payload validation error: ‘Additional properties not allowed: body (consider storing them in app_metadata or user_metadata. See “Users Metadata” in https://auth0.com/docs/api/v2/changes for more details)’.”,
“errorCode”: “invalid_body”
}

That’s weird. Have you tried using our Postman collection of our APIs endpoints for that?

Thanks It worked.
But when i tried a GET in postman its working but while i tried to POST create a user the below error is getting. But able to use GET not POST.
the body i used to create is
{

“connection”: “Initial-Connection”,

“email”: “t11@t1.com”,

“username”: “hi”,

“password”: “hi@123”,

“phone_number”: “+199999999999999”,

“user_metadata”: {},

“email_verified”: true,

“app_metadata”: {}

}
for that below response i got.
{
“statusCode”: 400,
“error”: “Bad Request”,
“message”: “The connection does not exist.”,
“errorCode”: “inexistent_connection”
}
